I have been having an issue with the stability track/reduced engine power coming on. I will be driving and then the reduced engine power with an exclamation mark pops up, my car speed drops and then the car cuts off. The car would crank back up after sitting for a while. After researching this, I found that several other GMC, Chevy and Cadillac had this same issue and were given the run around by GMC when trying to have it fixed. There was a recall for those vehicles but not the Terrain. I have had the throttle body cleaned like suggested and that did not solve the problem. The problem occurs no matter if I am on the highway or regular streets. Being a single parent of 3 and legal guardian of 1 grandchild, I don't have money to keep trying to repair this issue. I had my transmission looked at and that was not the issue. How can I get them to correct the stability track/reduced engine power issue? I have been without my car for a week now. This is making it hard to get back and forth to work. I am actually calling the GMC headquarters to report this issue and then the better business bureau.

ABS light is on even after fixing the supposed problem. System stabilitrak constantly on. Excessive use of oil. 2 to 3 quartz every 2 weeks. Reduced engine power comes up on dash and no matter how fast I am going (15 mph or 80 mph on a highway) it doesnt matter my car will slow down or just shut off. Also happens when I have to hit braked hard, slow down or accelerate from a stopped position. I am also using a lot of gas.

Car has been a nightmare since we purchased it. Constantly breaking down and having to result in expensive repairs. 3 catalytic converters, engine used to shut off due to overheating. Engine reduce sign, stabilitrak problems. This has been the worst car to ever be created in the history of vehicles.

I purchased my car used in September two weeks later I started experiencing stalling and erratic jerking while driving. I took the car to the dealer where I purchased the car (while it was under warranty) and was told not to worry it's just the O2 sensors. The car was loosing oil like crazy. December the car became worse and stalled and would not start. The dealership informed me I need a new engine, I am no longer covered under warranty and still paying for this car. No one will help me so now I'm stuck with a payment and an inoperable car.. oh did I mention I got a car fax once the car broke down to see the vehicle history the title is branded manufactor buy back/lemon.. I have seen on several forums and google that many people have complained and GM will not do a recall this issue is totally unsafe and can cause serious injury.

While drive down the interstate my car said service stability track then said engine power reduced, speed dropped dramatically then shut off completely. Engine would not turn back over. Had it towed to the shop only to find out the engine locked up due to no oil. Dealer said it was due to a very common problem with GM with excessive oil consumption! I had my oil changed and a full tune up 2 weeks ago! called to check recalls only to find out that in fact there was an recall for excessive oil consumption but my VIN wasn't involved. Dealer says in fact it should be! this could have caused a accident and caused my children and I to be seriously injured!

I was driving on the highway and the car cut off as soon as I slowed down getting off the exit. I started the car back up and it said that the stabilitrack was off and that I was losing engine power. I got to safety, checked my fluids and I had no oil in the car. But I changed the oil recently and had 3,000 more miles till my next oil change. I towed the car to my mechanic and described what happened. He told me that their was an internal engine failure that caused the timing belt to break. I called my insurance and they had a field adjuster look at the vehicle and he nor the mechanic could figure out why or how this happened on such a well maintained vehicle. They both stated that there is no way that I should have had 2 major system failures (I just replaced the transmission) with the current vehicle mileage. I called GMC and they will not so anything to help me. Their only solution is for me to tow it to a GMC dealership and they will look at it. I could've died in this car, I still owe on this car and they won't help me.

I have a 2011 GMC Terrain about 62390 miles. When I am accelerating the car jerks. I took it to the dealer they state they could not find nothing wrong. I just got the fuel pump replaced due to a recall. And now a light came on that read ac off due to high engine temp but the temperature gauge showed cold and it never went to normal after being on for 20 mins and to this day is goes to the notch right before normal. Also when the fuel is low the light does not come on. I called the dealership and they stated they have to duplicate the problem to fix it but I cant bring it in until 12/16/2016 because they are booked

My Terrain shut off the first time days after oil change while parked in a parking lot and running for 5 minutes. Days later while turning left at busy intersection to enter expressway it stalled and I barely rolled to side of road and was almost rear ended. Then a few days later while at a bus stop and ready to accelerate it stalled again. I had to restart. Dealership would not take any responsibility. Had to get over $3000 in work on engine.

While driving message read reduced engine power lost all power could not control the steering wheel! then the car shut down and continued to roll down the highway.almost got hit by other cars from behind. Very frightening for me I almost got a panic attack. I managed to stop the car on the shoulder of the road with half of the car still blocking other cars.car will not start. The battery is new.I have done research on social media and there's thousands of GM customers who have or are facing the same issues. Is this another cover up by GM that's continuously ignoring this problem and the consumers are paying thousands of dollars in this repair. I was told I need repairs that will cost $4000 dollars on a 2011 GMC Terrain car I got a year ago. This is ridiculous. Who is fighting for the consumers?

I bought this Terrain used with 21000 miles on it. I have had 2 issues with the stabilitrac system needing serviced since then. Both issues took place as I was starting the engine. I have many other complains of this vehicle. Certainly wish I had my 2009 acadia with 165000 miles back. I agree GM needs to do something.

During a normal commute on route on 2/15 received about 3 miles into the drive received a warning error - loss of engine power and the car would not accelerate. The car started shaking violently and received a stabilititrak error. The car was pulled to the side of the road and placed in neutral. The shaking became worse and the car was shut off. After two minutes the car was started again, with no issues and was driven 6 more miles without issue. After 6 miles of driving the same engine power warning and stabilitrack error came back. The car was violently shaking and the driver shut it off. It was towed to the dealership. The dealership received one code for the throttle sensor positioner. The code was reset and a loose connection was diagnosed as the fault and returned to owner. Five days later the car was started in the garage. Upon startup it started again to shake violently. The car was put in reverse and began to shake violently and the driver received a stabilitrak warning light. The car was shut off and was again towed to the dealership. The dealership found two codes crank position sensor and misfire. The car was driven five miles with no issues. The dealership cannot locate the root cause of the problem. This undiagnosed issue posses a severe safety risk to the owner of the car and family if it were to occur again while driving in congested traffic or on a highway.

I was driving on the highway at 60 mph and all of a sudden lost power. The reduced power and check stabilitrak messages appeared on the screen. I pulled over to the side of the road and turned the engine off. I immediately tried starting the vehicle again and it did, so went on my way. Got down the road about three miles and the same thing, so pulled to the side of the road and turned the engine off. I tried to start the vehicle, but there was no response, everything was dead. I waited several minutes and tried again and it started. I continued on my way and didn't have anymore trouble getting to my destination. A couple of days later, the same thing happened except when I tried to turn the vehicle off, it continued to run very roughly and then finally shut off. It did start again and had the engine light on. I've had the vehicle to the local GMC dealer when the first incident happened, however when they tried to read the codes, there were no codes to read even though the engine light was on. I was told everything checked out fine. I was down the to dealer again today with the engine light on again, but before they could check it out, the engine light had gone out. To me this is a very serious problem as it can very easily cause an accident. So far I've been lucky that I haven't lost the power steering or brakes.

I was driving on I-75 when all of a sudden my 2011 GMC Terrain slowed down tremendously. Also, the check engine light came on and the gage read engine power decreasing, service stabilitrak. I could have been killed and it was difficult for me to pull over to the shoulder. General Motors need to recall and fix this before someone gets killed. Come on General Motors. I just recently paid nearly $5,000 for a new transmission because the vehicle wouldn't move while in drive and had the catalytic converter replaced. Lots of problems with this vehicle.

I had oil changed that morning. That night, while driving, "engine power reduced" and "service stabilitrac" lights came on and vehicle would not accelerate over 15 mph. I had to pull to the side of the freeway and turn off the vehicle, wait a few minutes and try again. It was fine until the next day when the same thing happened again. It has been one week and has happened multiple times everyday since. I read many complaints on-line addressing this same issue and stating that it is the throttle body. I took it to the dealer and the diagnostic said the throttle body needs replaced. This is a safety issue! imagine traveling 70 mph down the highway, and you lose power to your engine! this is an accident waiting to happen!

Well it appears that there are several complaints on here about the 2011 Terrain stalling. It's been happening to me off and on the past several months. I would be in traffic and it would stall, I would be at a stop light and it would stall, I would go to back out of my driveway and it would stall. I took it in and they can't find anything wrong. Well last night it finally died. Great!! I heard noise when I started the vehicle that sounded like plastic water bottles rubbing together. I had a bag in my front seat so assumed it was nothing. It bucked forward as I put it into drive and stalled. Well...the stalling I'd become accustomed to so I re-started. It seemed fine until I went to accelerate onto the main road...it bucked, started shuttering, and wouldn't go above 5 mph. I barely got it into a parking lot before it died. I counted no less than 5 similar reports on here. I live in the metro detroit area...had this happened on a highway or during rush hour, I could've been killed. Someone needs to do something before GMC has yet another scandal on their hands or how many people have to be hurt, maimed, or killed before NHTSA gets involved??

Terrain 4-cyl

The same issue happened 3 times. November 2013, 28 January 2014, 16 February 2014. Each time the vehicle was in and idling situation red light, in a fast food drive thru, heavy traffic, or if I forgot something, left the car running, and went into the house to get what I was looking for, especially if it took me 4-5 minutes to find what I was looking for and return to the car. Additionally, I've experienced this moving at speeds of 8mph or less in thick traffic. (1) car would for no reason start rough idling. (2) the yellow check engine light would come on. (3) the engine reduced power message would appear. (4) the stabilitrak warning message light would then appear. (5) then I pressed the accelerator to cross an intersection and move out of the way of traffic, and the vehicle moves at a snail's pace (5-10 mph). (6) I let it sit for 10-30 minutes (or overnight if I was fortunate enough to be at home), restart it, and it runs like it normally does as if nothing ever happened. (7) the "yellow check engine light" simply disappears after a few hours. (8) sometimes there's a faint burning smell like a plastic garbage bag on fire, burning rubber, or overheated electronics. I'm taking it to my local GMC dealership today before I end up stranded somewhere or worse be the cause of a major serious accident! it's like it has a malicious code in the engine's computer system, and it selects the time and place when idling to inject itself! it may go several weeks or even months before it happens, but you can be confident it's going to happen! other than this annoying safety issue, the Terrain in my opinion is a pretty good vehicle for its class. Makes me wish I had chosen the 6 cylinder instead of the 4 cylinder. I don't think the 6 cylinder is having this issue. GM/GMC should address this, and make this right asap!
